HTML5 is the latest standard for browsers to display and interact with web pages. Approved in 2014, it's the first update to HTML in 14 years. In this day and age, that's a lifetime between updates.

The purpose of HTML5 is primarily to make it easier for web developers and browser creators to follow consensus-based standards that make compliance more efficient and empowering. It's also designed to provide better, faster, more consistent user experiences for desktop and mobile visitors.
